How to Maintain a 2003 Audi TT

1. Open your hood and remove the air filter. Hold it up to the light. You should be able to see through the filter. If you cannot, this means its dirty and needs to be replaced. The purpose of the air filter is to filter out any debris that enters the air system. This prevents damage to your engine. Dirty air filters can cause clogs in your hoses and your Audi will run poorly with inadequate air flow.
2. Check your brakes during tire rotations and changes. Brakes should be replaced when they are about 75 to 80 percent worn. Any more, and they can cause damage and scoring into your rotors, which will require rotor replacement as well. How often you need to replace your brakes depends on how much driving you do. More driving and frequent stopping wears the pads out faster.
3. Change the oil in your Audi TT every 3,000 miles or at least every three months to keep the oil fresh. The oil lubricates the moving parts of your engine and keeps it clean. The oil filter will need to be changed with each oil change. This filters out dirt and debris that can cause engine damage and sludge. Check the oil level in your Audi every month to ensure there are no oil leaks and that your oil is at the correct level.
4. Check the air pressure in your tires often. Especially between seasons when the temperatures fluctuate. This can cause a decrease in pressure, which causes pull on the tires. This can wear out the tread on your tires faster. Make sure tires are always fully inflated. Replace the tires once the tread is fairly worn.
5. Get a tune up every couple years. This involves replacing all the spark plugs, hoses, and belts even if they do not look worn. Also, have the coolant flushed and replaced with new fluid. This will head of any possible mechanical problems before they have a chance to start. This prevents any air leakage that you may not know about with old hoses or squeaky belts. It helps keep the engine running smooth.
6. Clean your Audis interior by vacuuming the seats and floors regularly. This will pick up any dirt or debris you may carry in on your shoes. It will keep it from getting ground into the fabric and causing stains. Wash the outside of your car often and apply a coat of wax a couple times a year. This will prevent fading of the paint.
